Objective To introduce a new method that abdominal puncture is used in ventriculoperitoneal shunt. Methods A retrospective review of the clinical materials of 49 patients who underwent improving ventriculoperitoneal shunt.Results After operations, all the patients had fellow-up survey that the rates of infection and obstruction are both 4.08%. They are lower than that of the lectures. Conclusion It has many advantages that abdominal puncture taken the place of incision of abdominal cavity. They are less wounded, less infection, less abdominal complication , not easy to be packed by the omentum and so on.

Objective To study the morbidity rule of community trauma and pre-hospital care mea-sures so as to improve the pre-hospital care performance. Methods 962 cases who received pre-hospital care by "120" commanding center in our hospital were retrospectively analyzed by means of self-designed questionnaires. Results The features of community trauma were mainly multiple trauma caused by traffic accidents, the main pre-hospital care measures included bandaging, hematischesis, pexia, aspiration of oxy-gen,intravenous injection, cardiopulmonary resuscitation,tracheal intubation and cricothyroid puncture,a-mong which bandaging, hematischesis and pexia accounted for 92.7 per cent. Conclusions Early and rapid treatments to the wounded patients, and correct medical rescue are very important. They are the two key factors to promote the success rate of rescue. At the same time, sound nursing management, correct medical treatment and nursing coordination are also critical aspects.

Objective To investigate the relationship between carotid intima-media thickness (IMT) and coronary atherosclerosis plaque through coronary CT angiography (CTA) in asymptomatic individuals.Methods Two hundred and fifty cases with CTA screened were selected in asymptomatic individuals,and according to the inspection result they were divided into no plaque group (detection of no coronary atherosclerosis plaque,180 cases) and plaque group (detection of coronary atherosclerosis plaque,70 cases).All cases were checked carotid IMT with B-ultrasonic.Results ANOVAs analysis showed that age and body mass index (BMI) had significant correlation with coronary atherosclerosis plaque (P ＜ 0.05).x2 test was used to show the smoking and family history of coronary heart disease had significant correlation with coronary atherosclerosis plaque (P ＜ 0.05).Univariate Logistic regression analysis showed that carotid IMT,systolic pressure,diastolic pressure,low density lipoprotein cholesterol,fasting serum glucose and creatinine had significant correlation with coronary atherosclerosis plaque (P ＜ 0.05).Multifactor Logistic regression analysis showed that carotid IMT had correlation with coronary atherosclerosis plaque (P ＜ 0.05).Conclusion There is significant relationship between carotid IMT and coronary atherosclerosis plaque in asymptomatic individuals.

Neuroblastoma (NB) is one of the most common malignant solid tumors in children, ranks fourth in the incidence of pediatric tumors, and accounts for 15% of pediatric tumor deaths in children in China. Despite the development of new treatment options, the prognosis for high-risk patients is still poor. An animal model that can replicate the tumorigenesis of NB is an important tool for the prevention and treatment of NB. However, there are currently no animal models that can simulate all features of human NB. To provide a reference for the construction of animal models and treatment of NB, this article introduced several animal models of NB that have been extensively researched: the mouse, chick embryo chorioallantoic membrane, and zebrafish models. At the same time, it elaborated on the species, construction methods, characteristics, advantages and disadvantages, and research progress in NB.
